This is a Sip trace Log from the VVX500 (220.127.116.114)
A break down of this log would be fantastic. This log shows call A coming to the phone, Answered, Placed on Hold, a second call coming into the phone, answered, and when we try to use the Soft key to emulate a call park or the basic transfer we have a failure.
With a single call initiated on the phone we can complete this all day long. The issue is when there are 2 or more calls on the phone we have failures transfering and parking.
Any help would be great!

Resolution: Please check => here <=
You log is not in debug and when briefly looking over it I can see a 487 Message.
Not knowing who your SIP provider is I can only suggest you work with their team to troubleshoot this. You should also use a currently supported software version like 5.5.2 or 5.4.6
